CPU Overheating after everything!

I've had this gaming computer for quite sometime now, and with it contained an AMD FX-8350 CPU and for the longest time i kept the stock cooler on. Even though it was really loud and quite warm when i put my hand up to after some time, it never really bothered me because it was not affecting my activities. I had bought an Arctic Alpine 64 Plus Cooler+Heatsink a while ago and had similar problems to my following situation, so i took it out and put the stock back. i never got to the bottom of it because I will admit i am quite lazy and the stock wasnt bothering me too too much. Recently i had the last straw when my computer overheated, completely shutting down and corrupting a save file i had in a new game (DARK SOULS III I dont know if that matters). So i put the new cooler in, and the CPU overheated again. I reapplied the thermal glue (TG-7) because i put a layer on it instead of just a pea sized amount, still didnt work. I tried removing the old old thermal glue and the most recent with alcohol this time instead of just a cloth, still nothing. I continuously removed and replaced the cooler to make sure it was in correctly. I even realized one of my 80mm case fans were on backwards and switched that. Currently my CPU idle temp is somewhere in between 23-30 degrees C, give or take a few. I can go into a game for approximately 20 min before it overheats again, rising to around 85. I was wondering if i should either switch out the new one with the stock (bc i did say i switched a fan around), buy a new cooler or one of you geniuses (no sarcasm intended) could help me with this. Thanks!

Some thoughts:

1) The Alpine 64+ is only rated for 100w CPUs. Your CPU is 125w, which suggests the Alpine 64+ is actually a less effective heatsink than the stock one.

2) Wrong fan speed profile could be part of this - if the fan isn't spinning up to full speed.

3) Poor cooler mount. You've mentioned you've remounted it several times though, and it's kinda hard to get wrong, so I doubt this is the case.

4) Poor case airflow. Does your case get warm to the touch when under load? If so, the air in your case isn't being cycled quickly enough, and you could lower temperatures significantly by improving airflow. A heatsink can't cool a CPU very well if it only has hot air to cool the CPU with.

5) Your motherboard might be...

I applied a pea sized drop in the middle of the processor then let the heatsink compress it. All fans are spinning. There were only 2 screws, but yes they are in tight

5) Your motherboard might be auto-overclocking or auto-overvolting your CPU. You can go into bios and try lowering voltage a bit. Maybe try -0.025v intervals, until it's no longer stable, then back off a little. This should lower temperatures a lot.

Thank you so much! I feel really stupid now because i only checked the socket compatibility and didnt check the the wattage. Do you by chance have any recommendations for a fair priced AMD compatible CPU Cooler?
